I have been using Elecrow for years as my PCB supplier for DIY projects, consisting of over two dozen designs. I have tried assembled PCBs as well so I thought of writing about my experiences with Elecrow and overall ordering PCBs from China. Recently I have started using JLCPCB as well and I will come back to that in another post at a later time.
Overall, I have been happy with the PCBs considering low prices. There has been occasional slight quality issues but these have been limited to silk screen and solder mask. I can recommend Elecrow but competition is tough though; some competitors offer even better prices and especially cheaper shipping.
